NEXT is a simple and easy-to-use app that allows high-quality calls without the need for personal information such as phone numbers or email addresses. With its unique technology, it provides excellent call quality even without a WiFi connection, eliminating the frustration of voice delays. However, the quality may be affected by server traffic and network traffic in the area.

When you first launch NEXT, you will receive a unique "MyID" for your personal use. To make an outgoing call, simply enter the recipient's "MyID" in the "Enter destination ID" field and then tap the "Voice call" button. To receive an incoming call, share your "MyID" with the other party and have them follow the same steps to call you. Note that if the "Notification settings" are turned off, you will not receive incoming calls when the app is closed.
